'GONQRETE RAILWAY-TIE.

Be it known that I, WILLIAM H. PRUYN, Jr., a.c1ti'z enof the United States, residing at Chicago, 111 the county of Cook and State of Illinois, have invented a certain new and.

useful Improvement in- Concrete Railway- Ties, of which the following is a specification.

My invention relates to railway tiesanll has for its object to provide certain new and useful improvements particularly, in connection with ties made of concrete or similar material. I

My invention is illustratediafit were, diagrammatically in the accompanying drawin s wherein 'gure 1 is a side view of atie with interior parts shown in dotted lines, Fig. 2 isan enarged detail, Fig. 3 is a cross-section on the line 3--3 of Fig.2, Fig. '4 is a side elevation of a modified form.

Like parts are indicated by the same letter in all the figures;

A is the body Bare the rails;'GC-are plates laid" upon the concrete material beneath the rail. These plates are pfeferabl I of the same width as the slightly big or than the thickness of t e edge dent to the y 40 ting the rail to tie and long enoug to support all the other parts. DD are clamping ates laid upon the sup orting plate C and a apted to overhang the so of the rail. Each of these clamping plates is rovided with a lower ortion of the base of the rail and an 11 per ortion projecting so as vto overhang the ase ut'not to be in ac'tual contact therewith.

nor rods for which I have found a convenient size is three-eighths of an inchin cross-section. They roceedfrom near one end of the tie to near t e other end, being turnedfup at the ends as indicated at F. Along the base of the tie are'a series of rods .GG, each turned atthe endin like manner as indicated at u G and each bent upwardly as indicated at G to form an arch in the middle of the tie.

J is an additional rod which maybe a little smaller. I have used one-fourth inch in formed beneath the point where the bolt cross-section. It lies immediately. abtge- 1 holes through the plates O and D pass. U I

wardl from this openi leads the bolt be e L. his opening is provided for the purpose of admitting the "bolt which is passed u wardly through the bolt hole, leaving tile. head-and associated washer inthe cup-shaped opening. When the. nut is forced home a ove the base flange of the. rail, the headof the bolt is'drawn up ainst the-top of the cup-shaped opening. I ere it is immediately beneath .the two reinforcing. bars. I provide for the on +shaped opening an associated bolt.'hol e and body lining M' which, referably in the shape oia contlnuous meta piece, lines bothcup-shaped the making'of the ties-t s metal lining and the rods are suitab'l supported in the mold and the material t on poured in until the mold is full, whereupon when the material. sets the tie is completed.

In oneform of my device shown in Fig. 4,

a igning and hole. In

the central portion of the tie is shownin an arched form, V the lower part being hollow ed out to'a do th of aboiibone and one-eighth the up er part being strengthened by a strengt eni mass about three feet long-and one and one alfinches thick.

As previously suggested, the size, reporltioriand arrangement of the severa parts ishestoward the .bottom. v

referably rounded as indicated. These COD-5 inch for a istance of about three feet and gurations, of course, will be followed by the u metal lining. The cup art is provided with the side flangesE E wiiereby it is convenientlysecured in the mold against theside thereof. The ,ining has been described and 5 will be referre to as 'a cup part. It will be obvious that it need not completely line the opening but forms at least lining for the upper part of the opening so as to distribute the strain exerted against the portion of the tie lying above the opening.

The use and operation of my invention are evident from the drawing and description. Imay add, however, that the rail seating Ipart or upper portion of the tie, and particu arly that portion which lies above the side opening, is reinforced in the case shown by at least two longitudinalrods. Just above the openings. it is preferably reinforced by another rod. To revent shattering of the concrete body a p ate is placed over such rail seat part beneath the rail; and to prevent direct contact between the concrete body ortion and the metal of the rail or its securmg devices, I providea plate to lie under the ra1l and a metal lining: for the opening and the bolt hole which leads up therefrom. Thus there is inter osed at every point between the rail and its securing part and the concrete-like body of the-tiemetal portions preferably presenting extended surfaces to the concrete to distribute thestrains. The rail must have an opportunity to move vertically. In the case of wooden ties it always doesso loosening the bolt sufiiciently for that purpose It also embeds itself in the tie. This latter action is obviated in the case of my tie by the plate interposed between the tie and the rail. WVhile the first action is permitted by the arrangement of the clamplng plate which, although in a fixed iosition, is not in absolute contact with the iiase flange of the rail. -The other points in the operation of the device will be sufficiently understood from what has already been said.

I claim:

In a railway tie, the combination of a body part of concrete like material with inwardly projecting cup like openings on its sides beneath the rail seating, part provided 56 with holes into such openingsextendingfrom such openings upwardly through thtie and securing devices i-n-suchholes which take against the u' -pe'1"inner part of the cup like opening and t 1 )per part of the base flange of the rail.
